- the device of the invention is arranged to lift a boat outboard motor 1 (shown by dashed lines in FIG. 1) and adjust its tilt; the motor 1 is connected to a swivel bracket 2 upperly hinged to a fixed bracket 3 rigidly secured to the stem 4 of the boat.
- the swivel bracket 2 and fixed bracket 3 are of conventional type.
- the swivel bracket 2 together with the motor 1 , can be swivelled upwards, as far as a position, indicated by dashed lines in FIG. 1, in which the motor is out of the water.
- the device comprises a lifting member 6 .
- the swivel bracket 2 is lowered (FIG. 2) and the motor is in the water, the inclination of this bracket and, consequently, the inclination of the motor to the fixed bracket 3 and to the stern 4 can be varied by adjustment members 7 .
- the device of the invention comprises a common support element 5 for the lifting member 6 , for two tilt adjustment members 7 , and for means 8 for feeding to said members 6 and 7 a pressurized fluid, for example oil, contained in a reservoir 14 .
- the lifting 6 and adjustment members 7 are of conventional type, each comprising (FIGS. 11, 7 and 8 ) a cylindrical body 6 A, 7 A within which a piston 6 B, 7 B is movable, to which operating rods 6 C and 7 C are connected.
- the pistons 6 B, 7 B divide the cylindrical chamber of the respective cylinders 6 A, 7 A into two half-chambers indicated by 6 M, 6 N and 7 M, 7 N respectively (FIG. 12 ), each connected to the device hydraulic circuit through apertures 6 E, F (FIG.
- the rod 6 C of the lifting member 6 presents at its free end a conventional cylindrical head 6 D, which is axially holed to enable it to be connected, by a hinge pin 28 (FIG. 14 ), to two walls 2 A (FIGS. 1, 2 ) of the swivel bracket 2 .
- the end 6 D of the lifting member rod 6 C can rotate with respect to the swivel bracket 2 , on an axis of rotation R 3 (FIG. 3) parallel to the axis of rotation R 4 (FIGS. 1 and 2) of the bracket 2 .
- the ends of the rods 7 C of the adjustment members are shaped to form a removable connection, preferably of male-female type, with the contacting surface 2 B of the swivel bracket.
- FIG. 13A shows, for example, a rod 7 C presenting a “fork” end 7 P (see also FIG. 5) arranged to engage with a pin 2 P extending from supports 2 M (shown partially) connected to that surface of the swivel bracket 2 facing the boat stem.
- the fork head 7 P and the pin 2 P are shaped such that while the adjustment members 7 are exerting thrust, the head 7 P and the pin 2 P are always in mutual contact without substantial slack.
- FIG. 13B shows a solution similar to the aforedescribed, and will therefore not be described in detail.
- the support element 5 (FIG. 9) is of substantially parallelepiped shape and comprises three distinct and separate seats or cavities 9 , 10 , 11 (FIG. 9 ), housing respectively the two adjustment members 7 and, partially, the lifting member 6 , a support seat 12 for the pressurized fluid reservoir 14 (FIG. 3 ), and a support surface 13 (FIG. 9) for the means 8 for feeding the pressurized fluid from the reservoir 14 , to the lifting 6 and adjust 7 members and vice versa.
- the seats 9 , 10 for the two motor tilt adjustment members 7 are shaped to house the members 7 without slack, these being rigidly and sealedly secured to the support element 5 by a plug closure element 15 (FIG. 3 ).
- the seats 9 and 10 are preferably inclined to the rear wall 5 A of the casing 5 .
- the longitudinal axis L of the adjustment members 7 does not intersect the axis of rotation R 1 of the casing 5 .
- the seat 11 of the element 5 in which the cylindrical body 6 A of the lifting member 6 is partly housed has a greater longitudinal dimension than this body, to enable it to partially rotate (through a portion of a revolution) about the axis of rotation R 1 of the support element 5 .
- This rotation as shown schematically in FIG. 9A, enables the cylindrical body 6 A to rotate, with its axis of rotation R 1 parallel to the front edge 11 A and rear edge 11 B of the seat 11 and coinciding with the axis of rotation of the element 5 , between two end positions.
- the lifting member 6 can move within the seat 11 between the two end positions F 1 and F 2 in which it is in contact with or close to the edges 11 A, 11 B of the seat 11 .
- a hinge pin 17 is used passing through holes 18 (FIG. 9 ), 19 (FIG. 11) provided in said support element 5 and in the cylindrical body 6 A of the member 6 .
- the pin 17 comprises a hole 17 A coaxial to the pin itself, to house a further central pin 17 A enabling the support element 5 to be connected to the side walls 27 (FIG. 14) of the fixed bracket 3 , such that said element 5 can rotate on an axis of rotation R 1 with respect to said bracket 3 .
- the pin 17 is also arranged to act as the rotary connection member for the conduits of the device hydraulic circuit provided within the element 5 and lifting member 6 .
- the pin comprises (see FIGS.
- FIG. 11 shows the mouths 6 I, 6 L of the two conduits 6 E, 6 Q provided in the body 6 A of the lifting member 6 and arranged to connect the two half-chambers 6 M, 6 N of the lifting member to the device hydraulic circuit.
- the pin 17 also presents, in its outer surface, annular cavities 17 G for housing usual seal gaskets, such as O-rings.
- the hydraulic circuit connected to the lifting member 6 and adjustment members 7 is shown in FIG. 12 and is of conventional type; it will therefore not be described in detail hereinafter.
- This circuit comprises a motor 50 for feeding a pump 51 such that the oil contained in the reservoir 14 can be pumped into one or other of the two half-chambers 6 M, N, 7 M, N of the lifting member 6 and adjustment members 7 .
- the circuit also comprises, as usual, a pilot valve 53 , a manual valve 54 to enable the boat motor 1 to be also rotated manually, a filter 55 and a plurality of overpressure or underpressure valves 56 .
- the pump 51 , the valves 56 , the pilot valve 53 and the manual valve 54 are housed in a box casing 90 (FIG.
- FIG. 3 3 ) rigidly secured to the element 5 , the motor 50 being rigidly connected to this box casing 90 (as shown in FIG. 3 ).
- the reservoir 14 is connected to the support element 5 , as already described.
- the reservoir 14 , the casing 90 and the relative components, the rotary connection member 17 and the lifting member 6 and adjustment members 7 are connected together by conduits 51 A, B, C, D formed within the body of the support element.
- conduits 51 A for connecting the reservoir 14 to the box casing 90 containing the main components of the hydraulic circuit
- conduits 51 B for connecting the upper half-chambers 7 M of the adjustment members to the reservoir
- conduits 51 C, D for connecting the rotary connection member 17 to the valve 53
- conduits 51 F, G for connecting this member to the half-chambers 7 N, 6 N of the lifting and adjustment members.
- the conduits for connecting together the components housed in the box casing 90 are not shown; advantageously, these are also formed by drilling the body in which said components are housed.
- the hydraulic circuit When the outboard motor is immersed in the water, i.e. is in its operating position, and its tilt to the stern is to be adjusted, the hydraulic circuit is activated to feed pressurized oil to the two adjustment members 7 and hence cause the relative operating rods 7 C to emerge from the support element 5 by a desired length, such as to vary the angle between the swivel bracket 2 and the fixed bracket 3 in the desired manner. Simultaneously with the feed to the adjustment members 7 , the hydraulic circuit also feeds the lifting member 6 . In this state the lifting member 6 does not however exert any lifting action on the swivel bracket. It should also be noted that during the adjustment of the outboard motor tilt, i.e.
- the support element 5 rigid with the adjustment members 7 , follows the rotation of the swivel bracket 2 . Consequently, during the action of the adjustment members 7 , the support element 5 rotates towards the stern of the boat or in the opposite direction, depending on the geometry of the swivel bracket and the connection with the rods 7 C. During this adjustment the lifting member also rotates about the axis of rotation R 1 of the support element 5 , but in a manner independent of the rotation of that element.
- the lifting member 6 is connected to the swivel bracket at a point different from that engaged by the rods 7 C of the adjustment members 7 , and can also rotate in the seat 11 provided in the support element 5 .
- This seat 11 is preferably shaped such that at the beginning of the adjustment stage, i.e. when the rods 7 C are within or slightly projecting from the element 5 , the lifting member is in the position F 1 (FIG. 9 A), with its front side close to the edge 11 A of the seat 11 .
- the adjustment member 6 instead lies in the seat 11 in the position F 2 (FIG. 9 A), i.e. with its rear side in contact with the rear edge 11 B of the seat 11 .
- the device is completely modular; in this respect, all its components can be secured to the element 5 independently of each other, and can hence be easily replaced if damaged or for maintenance, if required, or to assemble a device comprising components with particular technical characteristics.
- conduits of the hydraulic circuit are housed within the support element 5 and the box element 56 and are preferably formed by drilling the walls of these elements, they are protected from external agents and/or from possible damage and are not subject to wear.
- the second embodiment, shown in FIGS. 15A, 15 B, is substantially identical to the aforedescribed (elements common to the two embodiments are indicated in FIGS. 15A, 15 B by the numerals used in FIGS. 1 - 14 ).
- the axis of rotation R 2 of the lifting member 6 is not coaxial with the axis of rotation R 1 of the support element 5 .
- the lifting member 6 is movable rotatably within the seat 11 , so that during the motor angulation adjustment, i.e. during the operation of the adjustment members 7 , it rotates independently of the rotation of the element 5 and of the members 7 rigid with it.
- the element 5 also rotates in the same direction as the swivel bracket 2 , so that the heads 7 P of the rods 7 C reliably lie in the correct position when the swivel bracket 2 is lowered, i.e. in a position such as to be able to engage the counter-members 2 P of the swivel bracket 2 .
- a further embodiment could be provided similar to those already described, in which a support element of type similar to the described type 5 is provided, but in which the lifting member 6 is rigidly secured to said support element, whereas the adjustment members 7 are housed in one or two seats similar to the described seat 11 , i.e. in seats enabling the adjustment members 7 to at least partly rotate independently of the rotation of the element 5 and of the lifting member 6 rigid with that element, at least during the operation of said adjustment elements 7 .
- the axis of rotation of the adjust members 7 is preferably parallel to but not coincident with the axis of rotation R 1 of the element 5 .
- the rods 7 C of the adjustment members 7 instead of engaging the counter-members 2 P of the swivel bracket, could comprise usual flat heads arranged to act against usual bearing rollers fixed to the swivel bracket 2 ; using the said configuration, the device operates in a manner totally similar to the aforedescribed. It should however be noted that compared with the aforedescribed embodiment, there would be greater wear of those parts of the adjust members 7 and swivel bracket 2 in mutual contact.
- the support element 5 could be formed as a plurality of parts rigidly joined together to form a single body, or as several parts connected together.
- the device of the invention also advantageously comprises means 35 (FIGS. 15A, B) for measuring the angular position of the swivel bracket 2 . It is known to measure the position of the swivel bracket 2 by an encoder which measures the rotation of the hinge pin 28 of the swivel bracket 2 (FIG. 9 ). It has however been found that this arrangement is not totally satisfactory because of the small angle of rotation of the swivel bracket 2 during the adjustment of the motor tilt. According to the invention, measurement is made of the movements of a movable part, for example the piston 7 B or rod 7 C, present within the adjustment members 7 .
- a movable part for example the piston 7 B or rod 7 C
- the support element 5 presents, parallel to one of the adjustment members 7 , a cavity for receiving a conventional sensor able to determine the position of the piston 7 B.
- a conventional sensor able to determine the position of the piston 7 B.
- the reference numeral 35 A indicates a seat for housing a sensor for measuring the movement of the piston 7 B, and 35 B the seat for housing a usual circuit (not shown) for generating a magnetic field.
- the signal sensed by the sensor is fed to a conventional microprocessor control unit (not shown) for processing this signal and displaying the position of the bracket.
- the device and the method for measuring the angular position of the swivel bracket 2 can also be used in devices for adjusting the tilt of and lifting a motor of known type, and that the means for measuring the position of the piston 7 B and/or rod 7 C associated with it could be other conventional measurement means of a type usual to the expert of the art.
- the magnetic field generation circuit could be replaced by a permanent magnet secured to the piston 6 B.
- FIGS. 16, 17 , 18 , 19 and 20 show a further variant of a device of the invention in which the support element 5 is simplified, compared with the other aforedescribed embodiments.
- the variant of FIGS. 16-20 comprises a support element indicated overall by 50 which, as in the other aforedescribed embodiments, is connected rotatably to the fixed bracket 3 by a pin (not shown) passing through a hole 70 , to rotate on an axis of rotation L.
- the element 50 comprises a rear plate to which the bodies 53 of two adjustment members 7 , of type substantially equal to those already described, are rigidly secured, for example by screws.
- the bodies 53 present lower protuberances 53 A for housing a rotation pin 54 formed integrally with the body 55 of the lifting member 6 , of type substantially equal to that already described.
- the bodies 53 of the two adjustment members 7 and their end protuberances 53 A form a single element 50 similar to that indicated by 5 in the preceding embodiments, to which the lifting member 6 is connected in a rotatably movable manner.
- “seats” are identifiable for housing the adjust members 7 and lifting member 6 .
- the lifting member 6 can rotate within the space bounded by the bodies 53 of the two adjustment member 7 and by the plate 51 , the two adjust members 7 being secured to said plate 51 by connection blocks 65 A and respective seats 65 B.
- the member 7 has an inverted T-shaped outer body 55 , and presents a substantially cylindrical central part 57 provided with bands 56 A and ribs 56 B for stiffening purposes and/or for housing oil distribution channels, and, perpendicular to the central part 57 , two lower pins 54 comprising an aperture 58 for the passage of a further conventional pin (not shown) for hinging all the aforedescribed components to the fixed bracket 3 secured to the stem of the boat.
- the adjustment members 7 and lifting member 6 are of an identical type to the aforedescribed, and will therefore not be further described in detail.
- the oil reservoir 14 and the means 8 for feeding the pressurized oil to the members 6 and 7 are rigidly secured to the body 55 of the lifting member in conventional manner, for example by screws.
- the body 55 of the lifting member comprises in its interior a plurality of delivery and return channels for feeding the pressurized oil, by the means 8 , to the chambers of the members 6 and 7 and vice versa. More specifically, with reference to FIGS. 19 and 20, the body 55 presents a channel 60 A connected to the means 8 , and a delivery channel 60 B and return channel connected via holes 60 D, 60 E in the pins 54 to the adjustment members 7 and via the channel 60 F to the reservoir 14 .
- Similar channels to the aforedescribed are also present on the other side of the body 55 .
- the pins 54 are shaped similar to the aforedescribed pin 17 and, in addition to the said axial and radial return holes 60 C, 60 D and delivery holes 60 B, 60 E, also present annular cavities 61 for seal gaskets (not shown) and annular cavities 62 into which the holes 60 D and 60 E open, these being positioned and shaped such that when the bodies 53 of the members 7 are correctly positioned on the pins 54 , the cavities 62 are connected to the delivery channels 63 and return channels (not shown) provided in said body 53 .
- the hydraulic circuit of the device is identical to that already described with reference to FIG. 12 .
- the operation of the device and the feed of pressurized fluid to the members 6 and 7 are also identical to that already described.
- the rods 7 C of the adjustment members 7 are preferably within the interior of said members and are not “operating”, whereas the lifting member 6 is rotated outwards through a predefined angle, for example of about 4° to the bar 51 .
- the means and commencing pressurized oil feed to the hydraulic circuit when a first predetermined pressure is attained the adjustment members 7 begin to operate, whereas the lifting member does not exert any lifting action on the swivel bracket 2 .
- the body 55 of the lifting member 6 moves in accordance with the shape of the swivel bracket 2 , for example firstly in a direction away from the plate 51 and then towards this latter, whereas the adjustment members 7 do not vary their angular position during their entire activation period, forming one piece with the stern bracket 3 .
- the adjustment members 7 When the motor 1 is to be lifted, the adjustment members 7 present their rods 7 C completely extracted and the relative pistons in their end-of-travel positions, consequently on continuing to feed pressurized oil into the hydraulic circuit all the pressure acts on the piston of the lifting member 6 which by undergoing movement causes the desired upward rotation of the bracket 2 , with consequent lifting of the motor 1 .
- the body 55 of this member moves towards the plate 51 until it makes contact with it, after which the entire device rotates towards the stern 4 .
- means 35 are also provided in this variant to determine the angular position of the swivel bracket 2 .
- a sensor 80 for example a Hall sensor, arranged to measure the variations in magnetic field as the position of the magnetized piston 7 B provided inside the member 7 varies (the piston 7 B is either itself magnetized or comprises a magnet, for example a magnetic ring fixed to the piston).
- the signal from the magnetic field sensor is used by a control unit to calculate the angular position of the swivel bracket 2 .
- the pressurized fluid feed means 8 and/or the reservoir 14 are secured to the plate 51 and/or to the adjustment members 7 .
- said plate 51 and/or the body 53 of the members 7 present channels forming the hydraulic circuit necessary for the operation of the device.
